Section 1: Anatomy, Physiology, and Pathology of the Ear (Q1-Q20)
Q1: A 62-year-old patient presents with complaints of difficulty hearing in noisy restaurants despite wearing
hearing aids for two years. Real ear measurements show the aids are meeting target across frequencies. What
is the most appropriate next step?
A. Increase the overall gain of the hearing aids
B. Evaluate and adjust the noise reduction and directional microphone settings [CORRECT]
C. Recommend the patient purchase more powerful hearing aids
D. Refer the patient for a cochlear implant evaluation
Correct Answer: B
Rationale: Since real ear measurements confirm appropriate gain, the issue is likely related to signal processing in noisy
environments rather than insufficient amplification. Adjusting noise reduction strategies and directional microphone
settings is the correct clinical approach. Increasing gain could cause discomfort, and a cochlear implant referral is
premature without proper optimization of current devices.
Q2: A patient with a moderate sensorineural hearing loss is being fitted with bilateral receiver-in-canal (RIC)
hearing aids. During the fitting, the patient reports a plugged-up sensation. Which modification is most likely
to resolve this complaint?
A. Reduce the vent size on the dome
B. Increase the length of the receiver wire
C. Enlarge the vent or switch to a more open dome [CORRECT]
D. Turn off the feedback cancellation algorithm
Correct Answer: C
Rationale: The plugged-up sensation, known as the occlusion effect, is caused by trapped low-frequency energy in the ear
canal. Enlarging the vent or using a more open dome allows low-frequency sounds to escape, reducing this effect. Reducing
vent size would worsen the problem, wire length is unrelated to occlusion, and feedback cancellation does not address the
occlusion effect.
Q3: A hearing aid dispenser is performing a tympanogram on a new patient and obtains a Type B result with
a flat tracing and low ear canal volume. What is the most likely diagnosis?
A. Otosclerosis
B. Otitis media with effusion [CORRECT]
C. Perforated tympanic membrane
D. Eustachian tube dysfunction
Correct Answer: B
Rationale: A Type B tympanogram with a flat tracing and low ear canal volume is consistent with otitis media with
effusion, where fluid fills the middle ear space and restricts tympanic membrane mobility. Otosclerosis typically produces a
Type As pattern with normal volume, while a perforated tympanic membrane shows a very large ear canal volume.
Eustachian tube dysfunction often produces a Type C pattern with negative pressure.
Q4: During a hearing aid evaluation, a patient's pure tone audiogram reveals a bilateral, symmetrical,
high-frequency sensorineural hearing loss with a notched configuration at 4000 Hz. The patient reports a
history of occupational noise exposure. What is the most likely diagnosis?
A. Presbycusis
B. Noise-induced hearing loss [CORRECT]
C. Meniere's disease
D. Ototoxicity
